1KG spool holder

Spool holder I designed for multiple sizes of spools up to 3 ½" wide to be mounted above the printer on the bottom of a shelf. We use them for all of our 1kg spools and our 200 gram and 250 gram mini spools.  you only need to add a 4 ½" piece of ½" PVC or a 4 ½" piece of ¾" dowel rod or you could always print a rod to go between the 2 sides.
